Notes:
New Pt … H—N bonding modes in two cycloplatinated complexes, [Pt(C6H4CH2NMe2-2-C,N)(C6H4CH2NMe2H-2-C,H)Br] (1) and [Pt(1-C10H6NMe2-8-C,N)(1-C10H6NMe2H-8-C,H)Br] (2), were characterized by 15N-filtered and 2D NOESY 1H measurements. Both 1 and 2 show markedly different interactions of an RNMe2H+ group with a platinum centre; the 1J(15N,1H) values of 69 and 59 Hz for 1 and 2, respectively, are considerably less than those of the related free and protonated organic amine systems. The corresponding 1J(195Pt,1H) values are 72 and 180 Hz, respectively. An approach both to understanding and recognizing these Pt … H—N interactions is presented.
